Note: Full-res cross-section HERE, a bunch more shots of the interior (including plenty of terrifying glass-bottomed walkways) after the jump.

This is Mexican architecture firm BNKR Arquitectura's concept for a 65-story subterranean "earthscaper" right in the middle of Mexico City. Groundscraper, I would have called it a groundscraper. Also, a terrible place to be during an earthquake or when the mole-people attack. And they will.

Designed to be built smack-dab in the center of Mexico City, BNKR's Earthscraper wouldn't ruin the skyline there...and is designed in such a way that it would incorporate Mexico's history in its design. The top ten floors -- which, here, would be the "bottom" ten -- is a museum and cultural center dedicated to the Aztecs. Below that you've got retail space, then apartments and finally, deep underground, businesses. Because, you know, that's where business do their best work. It all terminates some 300 meters below the surface.

The shape of the building is actually an inverted pyramid with the interior hollowed out and a clear glass plate on top, so natural light can filter down to the areas below. Unfortunately, as much time as I spend in a dark room staring at a computer screen, I still don't want to live underground. I get claustrophobic. Also: really bad gas. I'm talking like, stain the walls green bad. You know what kind of security deposit they'd probably make me pay for an apartment down there? Asstromical.
